Of what Figure this Creature appear’d through the _Microscope_, the 32. _Scheme_ (though not so carefully graven as it ought) will represent to the eye, namely, That it had a large head AA, at the upper end of which were two protuberant eyes, pearl’d like those of a Fly, but smaller BB; out of the Nose, or foremost part, issued two horns CC, of a shape sufficiently differing from those of a blew Fly, though indeed they seem to be both the same kind of Organ, and to serve for a kind of smelling; beyond these were two indented jaws DD, which he open’d side-wayes, and was able to gape them asunder very wide; and the ends of them being armed with teeth, which meeting went between each other, it was able to grasp and hold a heavy body, three or four times the bulk and weight of its own body: It had only six legs, shap’d like those of a Fly, which, as I shewed before, is an Argument that it is a winged Insect, and though I could not perceive any sign of them in the middle part of its body (which seem’d to consist of three joints or pieces EFG, out of which sprung two legs), yet ’tis known that there are of them that have long wings, and fly up and down in the air. The third and last part of its body III was bigger and larger then the other two, unto which it was joyn’d by a very small middle, and had a kind of loose shell, or another distinct part of its body H, which seem’d to be interpos’d, and to keep the _thorax_ and belly from touching. The whole body was cas’d over with a very strong armour, and the belly III was covered likewise with multitudes of small white shining brisles; the legs, horns, head, and middle parts of its body were bestuck with hairs also, but smaller and darker. * * * * * Observ. L. _Of the wandring _Mite_._ In _September_ and _October, 1661._ I observ’d in _Oxford_ several of these little pretty Creatures to wander to and fro, and often to travel over the plains of my Window. And in _September_ and _October, 1663._ I observ’d likewise several of these very same Creatures traversing a window at _London_, and looking without the window upon the subjacent wall, I found whole flocks of the same kind running to and fro among the small groves and thickets of green moss, and upon the curiously spreading vegetable blew or yellow moss, which is a kind of a Mushrome or Jews-ear. These Creatures to the naked eye seemed to be a kind of black Mite, but much nimbler and stronger then the ordinary Cheese-Mites; but examining them in a _Microscope_, I found them to be a very fine crusted or shell’d Insect, much like that represented in the first Figure of the three and thirtieth _Scheme_, with a protuberant oval shell A, indented or pitted with an abundance of small pits, all covered over with little white brisles, whose points all directed backwards.
